STUD OR PROTECTOR FOR SPORTING BOOTS AND SHOES Dec. 24, 194-0.

Filed July 21, 1939 Patented Dec. 24, 1940 PATENT OFFICE STUD R PROTECTOR FOR SPORTING BOOTS AND SHOES William Howell Lewis, C'wmllynfell, Swansea, South Wales,

Application July 21, 1939, Serial No. 285,818

In Great Britain May 11, 1939 2 Claims.

This invention relates to studs or protectors for sporting boots and shoes, and has particular reference to the kind or stud or protector having spaced-apart conical holes therein for the reception of correspondingly shaped screws for securing the protector to the boot or shoe.

Such an arrangement, however, did not permit, when the stud or protector was worn down and required renewal, of the removal of the screws owing to their being correspondingly worn down and below their kerfs.

The present invention has for its main object the provision of a stud, the lower portion of which, when the stud and its securing screws are worn down a certain depth, automatically falls away so that portions of the screws are left upstanding from the boot or shoe, said portions then being readily removed by the aid of pincers or the like. go A secondary object of the invention is the reduction of the thickness of the stud at the central part thereof to enable the stud to be broken into halves, each of which is adapted to be screwed to the boot or shoe in any required position. 2 Accordingly, the invention provides a stud for sporting boots and shoes which broadly consists of an arcuate member, having in its underside a centrally disposed channel-section groove which extends the length of .the stud and with the inner faces of the walls of the channel bevelled to form sharp edges, and two conical holes for screw reception disposed one each side of the transversecentral line of the stud and at equal distances from said line and the ends of the stud. The stud is formed with a central transversely disposed V-groove in its upper face, said groove extending down the sides of the stud and across the sharp edges of the channel-section groove, so that the thickness of the stud is reduced and allows of its being broken into halves each of which is adapted to be screwed to the boot or shoe at any desired position.

This channelling of the underside of the stud permits of the same and its screws being worn down the thickness of the stud above the channel, whereupon the lower portion of the stud falls away and leaves portions of the screws upstanding from the leather so that said screw portions are readily removed by means of pincers or the like.

Further, when the stud is divided into two studs and are secured to the boot or shoe, the sharp edges of the walls thereof engage in the leather and prevent any turning of the said studs.

The invention is illustrated by the accompany-.

ing sheet of drawings, wherein- Figure 1 is a top plan view of the stud.

Figure 2 is an end view thereof.

Figure 3 is a sectional View, taken on line a, a of Figure 1.

Figure 4 is an inverted plan view of the stud. 5

Figure 5 is a side view of the stud.

Figure 6 is a sectional view, taken on line b, b of Figure 1 and showing the stud screwed to the leather of a boot or shoe.

Like numerals of references indicate corresponding parts in the several figures.

Referring to the drawin I represents the stud, 2 the channel-section groove in the underside of the stud and extending the length thereof, and 3 the bevelled sharpened inner faces of the walls of the channel-section groove, whilst 4 represents the centrally disposed V-groove which extends across the top of the stud and down the I sides and across the sharp-ended walls of the channel-section groove 2, and 3 represents the conical holes for the reception of the screws 6 which secure the stud to the boot or shoe. The broken line 1, shown in Figure 6, represents the depth to which the stud I and screws 6 have to be worn away before the lower portion of the stud can fall away and expose the upstanding portions of the screws.

Further, two spaced-apart rectangular gaps 8 are provided in both of the bevelled walls 3 of the channel-section groove 2, said gaps 8 extending the thickness of the bevelled walls and being disposed one each side of the transverse central line of the stud and at equal distances from said line and the ends of the said stud.

I claim:

1. A stud for boot and shoe soles, consisting of a substantially rectangular block of metal having a channel formed in the underface thereof, said channel extending from end to end of the block and occupying substantially the full width thereof, the walls of said channel constituting sole engaging portions and having relatively sharp edges, said block also having a transverse groove extending across the face of the block and down the sides thereof to form a weakening zone defining a breaking line, and a conical hole formed through each of the portions lying on the respective sides of said groove.

2. A stud for boot and shoe soles according to claim 1, wherein the walls of the channels are 50 formed with gaps, said gaps being so positioned relative to the transverse weakening groove that when the block is broken at said groove, each of the pieces so formed will have a gap in the center of the channel walls.

WILLIAM HOWELL LEWIS.
